Geography

Paleocoordinates:30.8° North, 79.3° West
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period:Paleogene Epoch:Oligocene
Stage:Rupelian 10 m.y. bin:Cenozoic 4

Age range of interval:33.90000 - 27.82000 m.y. ago
Stratigraphy
Formation:Suwannee Limestone
Stratigraphic resolution:bed
Stratigraphy comments: The section at this place revealed the existence of two beds. The lower bed consists of limestone composed almost entirely of large foraminifera but without observed mollusks. The upper bed contains molds of mollusks. There has been much slumping of the strata surrounding the sink, thus it is difficult to determine the original position of the upper bed, but it appears to be near the top of the section. The taxonomic list for this collection is restricted to the fauna of the upper bed. No unconformity is present between beds.
Lithology and environment
Primary lithology: lithified argillaceous "limestone"
Includes fossils?Y
Lithology description: several descriptions are in the paper from previous works: (1) cream-white soft limestone; (2) a lower white, finely granular, apparently pure limestone with few fossils and an upper limestone that is more argillaceous and carries an abundany fauna; and (3) the lower bed consists of a soft, white limestone composed almost entirely of large foraminifera but without observed mollusks. The upper bed contains molds of mollusks.
Environment:marine indet.
Taphonomy
Modes of preservation:cast,mold/impression
Size of fossils:macrofossils,microfossils
Collection methods and comments
Collection excludes:some genera,some macrofossils
Collection methods:field collection,survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:USGS
Collection method comments: Some foraminifera were identified in the sediments of the upper bed at this locality, but not all were identified to the genus level.
